In this paper we consider the propagation of 'sound' waves in water contained in flexible pipes, with the object of identifying which types of wall constraint are likely to be most effective in influencing the progress of a wave. It is well known that tube walls respond radially to unsteady fluid-induced pressures, and that teature explains why the wave speed falls below that of real sound. However, it is shown that these radial motions are inevitably associated with corresponding longitudinal vibrations of the pipe wall, and that for waves of long wavelengths the longitudinal vibration amplitudes are very much larger than the radial. Externally applied constraints which interfere with these longitudinal oscillations are therefore likely to be much more effective than those which interfere with the more obvious radial vibrations.(Wassmann)
